openmediavault vs TrueNAS

openmediavault is free software under GNU GPL v3 for building a network-attached storage system on Debian Linux, mainly in small and home offices. Web-based administration is intended to let users install and manage a NAS without deeper knowledge. Included file services are SSH, NFS, SMB/CIFS, and RSync. Storage features include software RAID, per-volume quotas, access control lists, and shared-folder snapshots on Btrfs. Monitoring provides syslog, watchdog, S.M.A.R.T., read-only SNMP v1/2c/3, email notifications, and process and system-state checks. Networking includes link aggregation, Wake On LAN, and IPv6. Plugins can add TOTP two-factor authentication, antivirus, USB backup, OneDrive synchronization, and Kubernetes through K3s. The Kubernetes plugin is required for the app catalog and containerized applications. Installation instructions cover Debian 13 or AMD64 bare-metal hardware, with updates through Debian package management. The project provides community support, documentation, bug tracking, and API documentation.

TrueNAS Community Edition is free storage software that provides file, block, and object storage through one interface. It uses ZFS capabilities including snapshots, replication, RAID-Z, and self-healing checksums. Listed services include SMB, NFS, iSCSI, S3 API compatibility, apps, Docker containers, and virtual machines. Administrators can manage it through a web UI or CLI and use SNMP, syslog, reporting, and the TrueNAS API. Security options include self-encrypted drives, dataset encryption, encrypted replication, WireGuard, OpenVPN, ACLs, and IP filtering. The maker lists integrations or certifications involving Kubernetes CSI, Proxmox, VMware, Veeam, Red Hat OpenShift, and others. The Community Edition is a free software download for x86 hardware, with support through forums, documentation, release notes, and bug ticketing. Professional support is described for Enterprise customers. TrueNAS publishes security advisories and recommends configuring systems according to its security best practices. Moving from TrueNAS CORE to Community Edition is a one-way upgrade.
